# Middle School Mathematics Department Summer Packet-Intro

advertisement Name: _______________________________

## Summer Packet-Intro

The Summer Intro Packet is designed for students to review material from their previous mathematics course so they are ready to begin the 8 th

grade Introduction to

Algebra & Geometry course in the Fall. The expectation is that the concepts contained in the packet are mastered

before

beginning the Intro course in August.

This packet is to be completed by the first day of school.

## Please note:

-Show All Work! – enough space has been provided on the packet itself, however, if you do not feel you have enough space to show your work on a given problem, please show your work on a separate sheet of paper. Staple any of your extra work to the packet.

-once finished, grade your packet and mark the appropriate box. Corrections should be done in a separate color to show difference

-if you need help with a concept, use the

phschool.com

website to

watch the tutorials or practice examples

-any of the topics can also be Googled and many tutorials are

available online

- a quiz will be given on this material the first week of school

Be prepared to be successful in 8 th

grade math by completing your packet this summer, and making sure you understand all of the concepts within the packet by the first day of class in August.

Good Luck!
